Help!

So my bf has been out of state for over a month and he just came back not too long ago. I got a positive ovulation test about 2 days ago and had some spotting. This didn’t occur with my last cycle especially since we didn’t have sex my last cycle even while I was ovulating during my last cycle. Could this be due to vigorous sex? Or ovulation spotting? My bf does have a large wiener and he tends to hit my cervix sometimes. I’m not crampy either. Also does it matter the time of day you have sex and how big his load is while ttc?
